We provide a detailed study of four marine Mesodinium species and compare the data to the companion article on Mesodinium chamaeleon and other available studies on Mesodinium, to shed some light on the taxonomy of the genus. Micrographs of two red phototrophic Mesodinium species, Mesodinium rubrum and Mesodinium major n. sp., as well as the first published micrographs of two heterotrophic species, M. pulex and M. pupula are presented in combination with molecular analyses based on the ribosomal genes. The main conclusion of this study is the invalidity of the genus Myrionecta based on the arrangements of the basal bodies forming the cirri and the separation of species formerly known as M. rubrum resulting in an emended description of M. rubrum and the description of a related new species M. major n. sp.
我们详细研究了四个海洋中双鞭毛原生动物属（Mesodinium）的物种，并将数据与关于 Mesodinium chamaeleon 的相关文章和其他关于 Mesodinium 的现有研究进行了比较，以期对该属的分类学有更深入的了解。本文呈现了两种红色光养性 Mesodinium 物种（Mesodinium rubrum 和 Mesodinium major n. sp.）以及两种异养性物种（Myrionecta pulex 和 M. pupula）的首次发表的显微照片，同时结合了基于核糖体基因的分子分析。本研究的主要结论是基于基体排列形成的纤毛和先前被称为 M. rubrum 的物种的分离，无效的 Myrionecta 属，这导致了对 M. rubrum 的修正描述和一个相关的新物种 M. major n. sp. 的描述。
